Set animation for ViewSwitcher programmatically

Question

I set the animation in the layout like this:

<ViewSwitcher
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:inAnimation="@android:anim/slide_in_left"
    android:outAnimation="@android:anim/slide_out_right" >

How can I do the same programmatically?

Answer 1

Please read the documentation for the ViewSwitcher class, it has two methods for setting the in/out animation:

// load the two animations  
Animation animIn = AnimationUtils.loadAnimation(context, android.R.anim.slide_in_left);
Animation animOut = AnimationUtils.loadAnimation(context, android.R.anim.slide_out_right);
// set them on the ViewSwitcher
vs.setInAnimation(animIn);
vs.setOutAnimation(animOut);

Answer 2

viewswitcher.setInAnimation(AnimationUtils.loadAnimation(context, R.anim.fade_in));
viewswitcher.setOutAnimation(AnimationUtils.loadAnimation(context, R.anim.fade_out));

Answer 3

You can skip the step of loading the animation with AnimationUtils and instead pass the anim resource directly:

switcher.setInAnimation(this, android.R.anim.slide_in_left);
switcher.setOutAnimation(this, android.R.anim.slide_out_right);
